Two-year-old boy is officially the world's youngest genius
At just two years and 182 days old - yes, the 182 is relevant - Joseph Harris-Birtill is the youngest-ever member of Mensa; the exclusive society for people with exceptionally high intelligence quotients.
Mensa, the world's largest and most recognized club for brainiacs, admits only those who score in the top 2% on standardized IQ tests — a threshold that starts at a score of 132.
'We hope that this accomplishment can give him a sense of pride when he is older – it's a very unusual accolade and the credit is all his!' mum Rose, who lives in the UK, told Guinness World Records.

Joseph said his first words at seven months
GWR and Joseph's parents have chosen not to reveal the toddler's exact IQ.
However, they have shared that he's surpassed the record of the youngest-ever Mensa member, a title previously held by Isla McNabb, who was awarded the honor in 2023 when she was two years and 195 days old.
To qualify for membership, individuals must demonstrate exceptional cognitive abilities in various intellectual areas, including problem-solving, logic and language comprehension.
Joseph's mum said: 'It soon became clear that he was an exceptional little being — he first rolled over at five weeks, said his first word at seven months, and read his first book out loud from cover to cover at 1¾ years."

"Kind, loving, confident and curious"
'By 2¼ years old, he was reading out loud fluently for 10 minutes at a time, could count to 10 in five languages, and could count forwards and backwards to well over 100.'
Joseph's world record should come as no surprise. His parents are academic professionals, and were able to see early on that Joseph's abilities were unusual for his age.
Rose, an honorary senior lecturer at the University of London, and David, a senior lecturer at the University of St Andrews, reached out to Mensa to get support for their son whom they knew was extraordinarily gifted.
'He loves a challenge and is really exhilarated by complexity, whether learning chess or poring over new words and concepts that he hasn't come across before,' Rose shared.
Joseph's family is proud of more than just his intellect, too. His mum noted that :
'He is very kind and loving, confident and curious, and incredibly determined.
"It is a common misconception that everything is super easy for gifted children. But everyone needs appropriate stimulation and understanding throughout their lives, and highly able learners can sadly have their unique talents dimmed by the pressure to fit into environments that simply haven't been properly designed for them."

Nuclear power: Expert reveals hidden cost of Australia's energy path
A leading British nuclear scientist has issued a warning to Australia that 'there are consequences' in rejecting nuclear energy as an energy source. Former chief scientific adviser to the UK Ministry of Defence Sir Robin Grimes said such a stance would likely put Australia in a weaker position to take advantage of the AI boom and invest in data centres. Sir Robin said the issue of nuclear energy was something Australia needed to 'debate', with the Coalition vowing to pursue it as part of its energy policy. 'Yes, you don't have to go nuclear, but there are consequences of deciding to use it and not use it,' he told NewsWire. 'It means that Australia will not be in as strong a position to do certain types of industrial processes. As a consequence, data centres, (AI and robotics) are much more difficult to have if you don't have that base-load capacity available to you.' A leading British nuclear scientist said there would be consequences if Australia chose to reject the use of nuclear energy in its grid. Picture: NewsWire/ Martin Ollman Sir Robin said while Australia was 'blessed with fantastic sunshine', nuclear should be considered as an alternative to costly batteries. In comparison, the UK generates about 15 per cent of its electricity from nuclear sources, with wind and gas also key players in its grid, accounting for 30 per cent of energy input. 'If you want energy security, and if you want a really robust system, then you're going to have to invest in phenomenal amounts of storage if you don't go nuclear,' Sir Robin said. 'Batteries don't generate energy. They're a tax on the energy that you're produced because you've having to store it … and the more energy you produce from intermittent renewables, the more storage you need and the greater the cost.' Australia's abundant supplies of uranium, which make up about 8 per cent of global production and are estimated to be about one-third of the world's uranium supply, could also be refined onshore, leading to new job markets, Sir Robin added. This could involve processing the uranium ore, refining it into yellowcake and converting it to uranium hexafluoride, steps that come before the compounds are enriched to create nuclear fuel. 'The question is, do you just dig the ore out the ground and shove it on a train and export it to somewhere that's going to do something with it, or do you go through some of the processes and retain more of the jobs associated with that in Australia,' Sir Robin said. Earlier this year, the Dutton-led Coalition took a nuclear policy to build seven reactors by 2050 to the federal election. Picture: NewsWire/ Martin Ollman Sir Robin's comments follow an Australia-first conference on nuclear energy hosted by the University of NSW in Sydney this week. The event featured talks from world-leading nuclear scientists, including Nuclear Energy Agency director-general William Magwood, US Department of Energy deputy assistant secretary Aleshia Duncan and Sir Robin. It follows the launch of Australia's first undergraduate honours degree in nuclear engineering, slated to start in 2026. UNSW's Nuclear Innovation Centre director Ed Obbard said he believed the nuclear debate would likely grow as Australia developed a domestic nuclear engineering workforce and through existing initiatives like the AUKUS submarine program and Sydney's OPAL reactor, which produces radioisotopes for medical imaging, cancer treatment and research. 'As the nuclear sector grows, both in Australia and worldwide, discussions on civilian nuclear energy will become increasingly realistic,' Dr Obbard said. 'Assuming that we still care about decarbonisation, nuclear is never going to go away.' However, Dr Obbard said Australia having a nuclear workforce was welcomed by both sides of politics. 'It doesn't matter whether you're Liberal and you think we need a workforce for a future nuclear workforce, or if you're Labor and you're desperate to find a workforce to show the Americans that we're doing OK with AUKUS,' he said. 'Or if you're a university where you have international students coming from around the world to study engineering at UNSW. 'You've got this tripling of capacity happening everywhere, and there's a huge nuclear skills shortage wherever you go, and everyone agrees on that.' The Coalition's energy spokesman Dan Tehan welcomed the conference and said 'having a conversation about zero emissions nuclear energy continues to be incredibly important for Australia and the world'. 'More and more countries are adopting nuclear energy as they seek energy abundance and to reduce their emissions, and this is something that should be on the agenda for discussion here in Australia,' he said. 'We've committed to the removal of the moratorium (on nuclear energy) and further policy is under review.'

Research uncovers unexpected benefits of snacking before bedtime
Put your feet up, relax in front of the TV and, almost inevitably, your stomach turns to snacking. To open the fridge or not is a question that plagues many afflicted by an evening attack of the nibbles. On the one hand are studies warning that to consume anything after 7pm – even after 5pm, according to one Columbia University study last year – is a route to metabolic disaster that will come back to bite us in the form of fat on the waistline, derailed sleep, disturbed blood sugar and raised risk of conditions such as type 2 diabetes. But is evening snacking as bad for us as we are led to believe? Reassuringly not all experts think so and some stress that we need a clearer perspective on the 'no night nibbles' rule. What you snack on, how close to sleeping you do so and what you eat during the rest of the day have a much greater bearing on health than a few squares of dark chocolate at 8pm, they say. For snackers – 95 per cent of UK adults have a snacking habit, according to research conducted at Kings College London (KCL) - that is welcome news. 'Not all night snacking is inherently bad and a nutrient-dense snack may even support better sleep for some people,' says Alex Ruani, a nutrition researcher at University College London and chief science educator at the Health Sciences Academy. 'Also, going to bed hungry can actually make it harder to fall asleep, especially if you had an early or light dinner, so a snack might offset that grumbling tummy.' In the KCL study snackers were shown to be healthier than non-snackers. 'They tended to have better BMIs and waist circumferences than people who don't snack at all,' says Dr Frederica Amati, research fellow and nutrition lead at Imperial College London's School of Public Health. And while the research did show that timing matters, it was less damning of evening intake than might have been expected. Only snacking after 9pm was associated with poorer blood markers – people who snacked at this time tended to eat sugary, high fat and more processed foods. 'It's less about 'the clock' and more about choosing snacks carefully and leaving enough time before bed, ideally avoiding eating immediately before lying down, as that can cause digestive discomfort or reflux that may disrupt sleep,' Ruani says. What about the weight gain associated with eating at night? 'Night snacks will mainly lead to weight gain only if they consistently push you into a calorie surplus,' Ruani says. 'But for some the right type of snack last thing may help to regulate appetite and reduce overeating the next day, which would have a positive effect on weight.' Of course, the message is to take your hand out of the tortilla chips packet and not to spoon ice cream from the tub last thing. So what do the experts do instead? Ruani snacks on cashews or pistachios 45 minutes to an hour before bedtime. 'I am convinced they help me to fall asleep faster, which I suspect is down to the natural sleep-inducing melatonin content of both,' she says. Amati says the trick is to plan ahead so that you avoid too much sugary temptation. 'We have young kids so tend to eat early and sometimes by 8.30pm I am thinking, hmmm, I might need something else,' she says. 'I make a date, crunchy peanut and dark chocolate bar to keep in the freezer or have dark chocolate almonds if I want something sweet, but there are plenty of options for healthy evening snacks.' Here's a guide to guilt-free evening snacking. What is the cut-off time for evening snacking? Trying not to snack after 9pm is ideal for most people who routinely go to bed between 10pm and 11pm, Amati says, but it's not a rule set in stone. 'If you have had a really busy or active day and are starving later on, then you are best off having a healthy snack than going to bed hungry,' she says. 'Equally, if you are going out for an occasional meal, don't miss out thinking there's a watertight cut-off beyond which you shouldn't eat.' Your body clock, or chronobiology, has an impact on when the best time is to stop snacking at night. 'For most people, eating after 9pm does have a negative consequence on metabolism the next day,' she says. 'However, if you are someone who routinely goes to bed later at midnight or 1am, then that threshold shifts accordingly and you might get the nibbles at 10pm.' Is an evening avocado going to boost my gut health? Eating avocados regularly has been linked to reducing everything from your risk of heart disease to the distribution of harmful belly fat and now it seems that as an evening snack they might have added value. Scientists at the University of Illinois found that snacking on avocados at night can trigger what they termed the 'second-meal effect', meaning that the composition of one meal affects how your body processes the next. The participants, all of whom were adults with raised blood sugar levels, were asked to eat either a whole avocado, a low-fat low-fibre snack or a processed snack designed to match the avocado's fat and fibre content between 8pm and 9pm each evening. It was the avocados alone that led the next morning to healthier metabolism of triglycerides, fats in the body that are a risk factor for type 2 diabetes when raised. Britt Burton-Freeman, professor of food science and the lead author of the study, said it was avocado's whole package – 'its whole-food matrix' – that produced the benefits and that avocados at night might also support general heart health. 'While the good fats and fibre in avocados already make them a satisfying snack, this research is making us think about how snacks before bed – something 84 per cent of people consume regularly – can influence how the body handles food later,' Burton-Freeman said. Will eating Greek yoghurt before bed really help to build strong muscles? A 2020 review in the journal Physical Activity and Nutrition showed that consuming at least 40g of casein protein, the type found in milk-based foods, approximately half an hour before sleep can aid muscle recovery and growth. However, there is an important caveat for most of us – it will only work if you have been lifting heavy weights in the hours beforehand. 'Yes, you do need to do the exercise first,' says George Morris, an exercise physiologist based at St Mary's University, Twickenham. 'The same benefits don't come if you just eat protein and do nothing.' There's evidence that we absorb more amino acids from protein when we sleep, Morris says, and if you are over 60, eating yoghurt or another form of protein in the evening might be even more beneficial. 'We get a bit less efficient at absorbing protein and distributing it throughout the day in later life,' Amati says. 'Having something like a yoghurt or oatmeal with kefir at night might help to maintain the nitrogen balance that is important for protein metabolism over the 24-hour period in your sixties and seventies.' Are pistachios the ultimate night-time snack? Most nuts are good for us and, within reason, snacking on them boosts diet quality, helps to protect against heart disease and, according to a 2025 study published in Clinical Nutrition improves the health profile of adults at risk for metabolic disease. But what about eating nuts at night? Amati says she keeps Kilner jars of nuts on standby in her kitchen in case of an evening snack attack and Ruani favours pistachios, recently shown to be a winner in the war against type 2 diabetes. It is sometimes recommended that adults with prediabetes, defined as higher than normal blood sugar, eat a night-time snack of 15-30g carbohydrates, such as one or two slices of wholegrain bread, to regulate blood sugar levels overnight, the scientists said. For her study in the journal Current Developments in Nutrition, Kristina Petersen, associate professor of nutritional sciences at Penn State University, asked 51 participants with the condition to consume 50 grams of pistachios each night instead. After three months, there were significant improvements to their microbiome including a rise in 'good bacteria' such as Roseburia and Lachnospiraceae. These beneficial bugs are known to produce short-chain fatty acids such as butyrate, an energy source for gut cells, which helps to maintain a healthy gut barrier and to reduce inflammatory processes that exacerbate metabolic disease. 'Pistachios seem to be able to meaningfully shift the gut microbial landscape in adults with prediabetes, especially when consumed as a nighttime snack,' Petersen said. 'These microbiome changes may offer other long-term health benefits, potentially helping to slow the development of type 2 diabetes or to reduce systemic inflammation.' I've heard that eating cottage cheese at night will aid recovery from workouts Eating two tablespoons of cottage cheese before bed was shown to have a positive effect on repair and regeneration of muscles and on general health, with no negative effect on metabolism or hunger levels the following morning. In a study of active women in their twenties at Florida State University, physiologists suggested that cottage cheese is as effective as commercial protein shakes and supplements - only much cheaper. 'Cottage cheese is another source of casein, a slow-digesting protein that supports overnight muscle repair, particularly useful if you're very active,' Ruani says. Should I take a banana and warm milk to help me sleep better? It's a combo that was shown in a 2024 study by health scientists in Turkey to improve sleep, regulate appetite hormones and reduce insomnia. Rhiannon Lambert, a registered nutritionist and author of The Science of Plant-Based Nutrition, says bananas and milk both contain tryptophan, an essential amino acid that serves as a precursor to serotonin and melatonin, neurotransmitters that help regulate mood and the sleep-wake cycle. 'Milk also provides calcium, which helps the brain use tryptophan to manufacture melatonin more effectively,' Lambert says. 'Additionally, bananas are rich in magnesium and potassium, minerals that support muscle relaxation.' The Times Read related topics: HealthNutrition
